The heavy version has 27 first stage engines (9 on each booster and 9 on the cor stage). Then in the table for the falcon 9 they list 13.5 engines. I think the the aditional 4.5 is referring to the additionally thrust the engines produce. The table also list 2 second stage engines but everything I have heard is one with a larger more efficient vacuum nozzle. 0 ▲ 0 ▼ Reply Actions Alwin Barni in reply to Enrique Moreno f I read the source and it is ve... more » 21 hour(s) ago reuse-and-relaunch-a-dozentimes.html#sot_0c4465a7170d432844a902c027dfb09c97 ( 9-block-5-targets-24-hour-turnaround-no-refurbishment- 06cdbc) Exactly. This 'one Merlin engine' makes me question the quality of this article entirely (and unfortunately others as well). It does not seem possible to have enough thrust with one engine, and as for the second stage - it does have only one. If it was Raptor, then maybe, but still it would be entirely different rocket.

If it has one engine then it can't be a Falcon 9 as the number denotes the number of engines. Except that Falcon Heavy won't be called Falcon 27, for rather obvious reasons. 0 ▲ 0 ▼ Reply Actions reuse-and-relaunch-a-dozen- times.html#sot_e8d2089517d12111f4ece670352db54988 vl hc 1 day(s) ago ( targets-24-hour-turnaround-no-refurbishment-reuse-and-relaunch- a-dozen- times.html#sot_a46853bfdef31b18eea41833b075b195aa2fe420) The great thing about not going public is you don't have to release your finances, gives fans a lot more room to fantasize about profit. Just imagine how much more "profit" Tesla would be making, at least according to fans, if they can also keep financial data a secret.
